A literary celebrity by the age of 25, Goethe was ennobled by the Duke of Saxe-Weimar, Carl August in 1782 after taking up residence there in November 1775 following the success of his first novel, The Sorrows of Young Werther. He was an early participant in the Sturm und Drang literary movement. During his first ten years in Weimar, Goethe was a member of the Duke's privy council, sat on the war and highway commissions, oversaw the reopening of silver mines in nearby Ilmenau, and implemented a series of administrative reforms at the University of Jena. He also contributed to the planning of Weimar's botanical park and the rebuilding of its Ducal Palace, which in 1998 were together designated a UNESCO World Heritage Site.
His first major scientific work, the Metamorphosis of Plants, was published after he returned from a 1788 tour of Italy. In 1791, he was made managing director of the theatre at Weimar, and in 1794 he began a friendship with the dramatist, historian, and philosopher Friedrich Schiller, whose plays he premiered until Schiller's death in 1805. During this period, Goethe published his second novel, Wilhelm Meister's Apprenticeship, the verse epic Hermann and Dorothea, and, in 1808, the first part of his most celebrated drama, Faust. His conversations and various common undertakings throughout the 1790s with Schiller, Johann Gottlieb Fichte, Johann Gottfried Herder, Alexander von Humboldt, Wilhelm von Humboldt, and August and Friedrich Schlegel have, in later years, been collectively termed Weimar Classicism.
